its a 2010 model I believe. there's no disk. and no power to test it, period. I hear the PSU humming but when I press the power button on the back....nothing happens. I called my nearest Mac repair center and they told me " it's the power supply that's bad....bring it in to us..." which I can't because the iMac is one of my clients'. so right now I have the whole thing taken apart, the logic board and all and i'm re-checking everything one inch at a time. my next guess is the logic board is bad. I also notice one of the 4 l.e.ds light up when I plug it in LED501 but nothing else happens. I've done some looking around online and I found some articles talking about what it means but no discussions on how to go about fixing it....
